IBM this week announced in a Securities and Exchange Commission (SEC) filing that it was under fresh investigation by the US Department of Justice (DOJ) for offences covered by the Foreign Corrupt Practices Act of 1977 (FCPA), according to online anti-corruption site, fcpablog.com.

The tech giant came to terms with the SEC in March 2011 over accusations of corruption by employees in IBM Korea, LG IBM, IBM (China) Investment Company Limited and IBM Global Services (China) Co., Ltd., between 1998 and 2009. Under the agreement IBM was required to pay $10m in penalties, which was made up of profits accrued as the result of the alleged activities, prejudgment interest and a $2m civil penalty.

The FCPA covers a number of issues, but according to the FCPA Blog the accusations leveled at IBM's overseas units involve transparent accounting practices and the bribing of public officials.

Last year a federal judge, Richard Leon, whose approval was required to cement the SEC-IBM settlement, rejected the proposal and asked for more information regarding accounting practices. Previously, only bribery had been under investigation.
